Graphene: A miniature bulletproof vest?

Materials Science To stop a speeding projectile, you need a combination of strength and toughness so that the impact doesn't just pierce the stopping material. The material also needs to dissipate the absorbed kinetic energy. Lee et al. measured the response of multilayer graphene to the projection of microbullets using miniaturized ballistic tests. The findings confirm graphene's exceptional strength and stiffness. Science , this issue p. [1092][1] [1]: /lookup/doi/10.1126/science.1258544
